How to store data from Ionic app on the servers?

[pegetive]

Hi,

I have implemented an app for Fitbit Ionic using Fitbit Studio. The app is a simple game but I don't know how I can store data when a user is finished with the game. I'm new to the Fitbit app development. Could some one tell me how I can store the game data? Thanks a lot.

Have a look at onunload and the File System API.

Thanks. Can I get access to the files after my app is published? And if yes, is it possible to read the files via the web API?

Such files are stored on the watch. If you want them elsewhere, you have to use File Transfer to get them to the companion; then you can use fetch or WebSockets to send them to a server.

Thank you. I also have another question. What happens if I use file transfer to send a json file from the app to the companion but not send it to a server? Can I still get access to the json file after the app is published by Fitbit?

Publishing the app won't make any difference to your ability to access data. That's the good news.

The bad news is that the file on the companion isn't accessible outside of the companion. You can't get at it using a file manager. Even inside the companion, it's really more like a variable in memory than a file in storage.

Ok, thanks. So in order to store my data that is communicated through
companion, I should store the data to a server right after receiving the
file via companion. Right? I just want to store users game data somewhere
accessible.

Yes, I'm afraid so. If you really want an on-companion-device solution, you could send it to a 'server' running on your companion device; ie, a local program that can intercept the fetch() or WebSocket output from your companion code.

Thanks again. I also have another question. To send a file to a server, is
it possible to do it via the app itself rather than the companion?

Sorry. 😞
